Landlord of the Tang Dynasty

Chapter 370 Coke Ironmaking (2)

Passing through the boilers, Xu Qing saw that there were about ten people in each boiler. From lighting the fire, carrying water, to beating, each of them performed their duties and carried out the casting of this weapon in an orderly manner.There could be room for five boilers in one house, and Jian Cheng led Xu Qing through more than a dozen houses, and arrived at a house marked "Army Supervision".Xu Qing knew that this was where Jian Cheng's yamen was located.

Jiancheng said, there is no hospitality here, please go directly to the workshop.Xu Qing didn't come to drop by, so he nodded in agreement.But Jian Cheng led Xu Qing to a workshop. There was only one boiler in this room, but there were guards guarding the door.Jiancheng told Xu Qing that this place is for studying how to improve smelting and forging technology, Xu Qing thought, isn't this a science and technology park?That's right, the equipment in this place where science is done is definitely much better than those where production is done outside.

After Jiancheng's introduction, Xu Qing and the load of coal that Xu Qing brought were left behind.An old man by the boiler came over, cupped his hands and said, "Old Lu Xuan, see Mr. Xu."

Xu Qing thought, this old man is so arrogant, he is so proud of this self-proclaimed "old man".Most of the craftsmen in this military prison are ordinary people, and they should be humbled when they see Xu Qing.The word old is a modest term, but because of the word "old" in it, this modest term has changed its flavor.Old man, Taiya, although you call yourself a rotten wood, you also call yourself an adult.

However, Xu Qing pretended not to know, and instead respected him: "This old man must have superb skills. I have some new ideas. I want to experiment here. Is it possible?"

Lu Xuan smiled: "Mmmm, there is nothing worthless under the prestigious name. It is indeed Mr. Xu Qingxu who is rumored to be crazy, and he is very good when he speaks."

Xu Qing smiled and said: "The rumors outside are so exaggerated, I'm really ashamed."

Lu Xuan shook his head and said: "Master Xu's method of making ice with saltpeter, horseshoes, I know, Master Xu really has a fantastic idea, and the old man is also yearning for it, but I only have some experience in making iron here, I don't know Master Xu You came today, but you came here to make iron?"

Xu Qing nodded: "The reason why I came here today is to make iron. I wonder if Mr. Lu is free now?"

"Since Mr. Xu is here, and the idea of ​​the old man has just encountered a problem, let's hear what Mr. Xu thinks first?" Lu Xuan said, and the people around him were all preparing to make iron smelting.

But Xu Qing stopped him and said slowly, saying that he was not in a hurry to smelt iron. When they were puzzled, Xu Qing pondered and asked: "Mr. Lu, do you know the four characters of perfection?"

Lu Xuan's eyes lit up when he heard it, and then he said: "The furnace is perfect, haha, I have heard of it. But the furnace is mixed, I have seen it before, Mr. Xu may not know, I wait for iron smelters to forge iron in the furnace." Green fire is the best, a furnace of iron can have five or six strands of green fire, and it takes half a stick of incense to burn, then this iron must be of the highest quality..."

Xu Qing asked again: "Mr. Lu, I have a question for you. I hope you don't get angry. Dare I ask how much green fire you can make?"

Lu Xuan was stunned and said: "No talent, as long as there is a good ore, the ten wisps of green fire are still guaranteed."

"Hahahaha..." Xu Qing laughed suddenly, and Lu Xuan asked puzzledly:
"Master Xu, why are you laughing? Are these ten traces of green fire not enough? Oh, of course, the more the better, but in today's world, the only one who can refine more green fire is the old man Yuan Tiangang."

Xu Qing said decisively: "Mr. Lu, it's not me, Xu Qing, who is talking big. Wait a moment, I will make a furnace full of green fire for you!"

"what?!"

Lu Xuan looked at Xu Qing as if he saw his best friend cheating on him, but he is not living in vain at such an age, the firmness and confidence in Xu Qing's eyes should not be a lie.But this full furnace of green flames was his lifelong pursuit, the pursuit of several generations of the Lu family.It's just a wish that Xu Qing can do it now?
I don't believe it, no matter how powerful you Xu Qing is, I don't believe it today.Lu Xuan looked into Xu Qing's eyes and asked seriously: "Master Xu, do you think this is your fantasy, or have you already made it and changed it to the cauldron experiment here?"

Xu Qing thought for a while and said, "For the time being, it's just my fantasy, but I have [-]% experiment."

This time, Lu Xuan heaved a sigh of relief. He thought to himself, the old man has had a new idea every day for decades, but has the old man succeeded?Is the old man inflated?Is the old man proud?The old man never said that he was [-]% sure,

Seeing him like this, Xu Qing said, "Mr. Lu, can you control the temperature in the furnace?"

"As for the temperature in this furnace, the old master's disciples can do it." Lu Xuan said with a light smile, "However, the old master will figure it out for you personally, and see how your furnace full of green fire is made."

Without saying a word, Xu Qing looked around the boiler and found that there was a ventilation hole on the boiler, then shook his head, the coke needs to be produced in a sealed environment.So he said to Lu Xuan, "Can you block that hole?"

As soon as this remark came out, everyone present laughed, and Lu Xuan also laughed so that his white beard trembled. He looked at Xu Qing and said, "Master Xu, if you block that hole, how can the fire start?" ?”

Xu Qing replied seriously: "Use charcoal, pile some red-hot charcoal in it. Be sure to block that hole, otherwise today's matter will not be possible."

Then, Xu Qing pulled the old man Lu Xuan aside, and made a general request.Wait for the charcoal in the furnace to burn red, and then pour the coal into it, and then cover the furnace cover tightly, and cover the vents to prevent a trace of air from entering.Lu Xuan couldn't resist Xu Qing, so he started to think of a way, and after a while, the people in the workshop started to move.

Lu Xuan personally commanded, and Xu Qing came up with some temporary ideas. Although this was the first time he came here, it took only a short time for the preparations to be made.After the charcoal was set, Lu Xuan put some fluffy straw in it, and lit the fire.I don't know how Lu Ban knew that the charcoal inside was all red, so he ordered his men to build a small bridge that was originally erected, like a plank bridge like water-carrying sports, and then poured two large barrels of coal into it.

Then, someone shut down the big boiler, and someone brought an iron plug to block the vent.

At this moment, Xu Qing's heart thumped. He knew the basic conditions for coal to turn into coke, [-] degrees and a sealed environment, burning and volatilizing the magazines and other organic substances in the coal, leaving relatively pure carbon that can be burned.However, I don't know if other aspects of this boiler can meet this condition, and the original air in the boiler will also have a great impact.Xu Qing only brought two barrels of coal, and wondered if he could burn a barrel of coke.

However, as long as there is coke, steel can be made immediately, so for the sake of steel, wait patiently!
